Abstract: We present a multi-robot model suitable for study of interactions and emergence of rational behavior. We focus on a grammatical approach, and to demonstrate its advantages, we design a model of an adaptive multi-robot community in terms of eco-grammar systems. We show that this grammatical model, based on the blackbord architecture, can naturally involve reinforcement collective learning. We test two learning algorithms in a common environment with almost reactive co-operating robots. Experimental results show that using …the grammatical model, the robot community can be successfully trained to find a close-to-optimal solution to a given NP-complete task of a truss construction.

Abstract: Metalinear CD grammar systems are defined to be context-free CD grammar systems where each component consists of metalinear productions. The maximal number of nonterminals in a starting production is the width of a CD grammar system. It will be shown that the width of metalinear CD grammar systems induces an infinite hierarchy of language classes. In addition, it is established that metalinear CD grammar systems of a certain width generate language classes that do not contain …all context-free languages but contain some context-sensitive languages. The resulting language classes are closed under union, intersection with regular languages, homomorphism and inverse homomorphism. They are not closed under concatenation, Kleene closure, intersection and complement. Show more
